In 1939, ten tempura color murals were commissioned by the Alabama Cooperative Extension Service to be part of an exhibit at the Alabama State Fair. The ten murals, titled "Historical Panorama of Alabama Agriculture," pained by John Augustus Walker of Mobile, depict a colorful visual representation of Alabama's agricultural history. The murals range in size from roughly five by seven feet to slightly smaller, depicting theme of farm efficiency, economy, and opportunity, as well as milestones in Alabama's agricultural history. The murals were intended to be the backdrop of a larger exhibit displaying fresh produce, farm implements, baked goods, quilts, informative signs, and "modern" farm technology.

Following the fair, the murals were exhibited at the Louisiana State Fair and eventually were stored and forgotten in the attic of the State Extension headquarters building on the campus of Auburn University.

In 2006, the Alabama Cooperative Extension System rediscovered the historically significant New Deal era murals, and they became a focal point of Auburn University's sesquicentennial celebration.
